During the ice age, sheets of ice extended from Canada into the northern half of the US. While these glaciers were moving south, they picked-up chunks of Canadian granite, rolling it under mile thick ice and deposited this rock in Wisconsin. Then as the ice sheets melted, huge amounts of melt water flowed over these granite chunks smoothing and rounding them further, making what is now known as the Wisconsin Cobble. These Cobbles, sometimes referred to as river rocks, fieldstone or granite boulders, are made of the now smooth and rounded granite. Ranging in size from a few inches to several feet across, they come in a mixture of colors, from a deep rose, to pink, buff, black and even white. Some are striped, some are spotted, and some even have swirls of different colors. Available in three sizes, these cobbles are great for ponds, borders and small retaining walls. Wisconsin Cobbles are an economical and easy way to enhance the beauty of your yard or garden.
